The cushioning support pads may be used with a bra garment or with other garments such as swimwear and other apparel where bra support pads can be incorporated.

The present application is a continuation of U.S. application Ser. No. 17/329,790, filed on May 25, 2021, which is a continuation-in-part of U.S. application Ser. No. 17/009,133 filed on Sep. 1, 2020. This disclosure relates generally to a bra garment and more particularly to bra garment formed of sustainable materials, including improved bra pad portions formed of bio-based polymeric foam materials, that as contrasted with petroleum-based foam pad materials, are recyclable, biodegradable and/or environmentally sustainable.

BACKGROUND

Bras are commonly worn by women to provide support for their breasts and for enhanced shape and appearance. Other garments have built-in bras and can provide the same function. Proper support for the wearer is important for bras and thus dictates the type of materials that can be used, particularly for the pads of the bra used for shaping and support as desired, which are typically formed of petroleum-based polymeric foams that are not recyclable or biodegradable. As such, foam pads are usually attached to the bra using a glue. The foam material and glue, however, can be toxic to the wearer and is not recyclable or environmentally friendly. There is therefore a need for improved environmentally friendly bra garments, particularly bra garments having foam pad portions formed of recyclable and biodegradable materials to make bra products more environmentally friendly and sustainable. The improved recyclable and biodegradable support pads of the present invention may be used with a bra garment or with other garments such as swimwear and other apparel where bra support pads can be incorporated.

SUMMARY

The present disclosure may provide a sustainable bra garment that comprises first and second cup portions that include bra pad portions formed of one or more bio-based polymeric foam materials and first and second side wing panels that are formed of recycled flexible materials and extend from the first and second cup portions, respectively. First and second cushioning support pads are configured to be coupled with the first and second cup portions, respectively. Each of the bra pad portions has front and back surfaces wherein the front surface of each pad that has a generally convex shape and the back surface of each pad that has a generally concave shape. Each of the pads is formed of a sustainable material that has hardness and density values that provide both cushioning and support to breasts of a wearer of the sustainable bra garment. The pads formed of a sustainable material may also be used within other types of garments and apparel, such as sports bras, swimwear, camisoles, bustiers and other apparel where bra support pads can be incorporated.

In certain embodiments, the sustainable material is a bio-based material, such as a sugar cane-based polymeric foam material (known in the art as a “green-EVA” material) that is non-toxic to the wearer.

DETAILED DESCRIPTION

Referring to the figures, the present disclosure generally relates to a bra garment 100 formed of sustainable and recycled materials that is environmentally friendly, non-toxic to the wearer to promote health and wellness, and can be manufactured at a reduced cost. The bra garment 100 may be, for example a bra, sports bra, a maternity bra, a brassier, a bikini top, a camisole, other lingerie top, or other breast covering garment, such as swimwear.

The bra garment 100 may generally comprise cup portions 102 a, 102 b, side wing panels 104 a, 104 b extending from the respective cup portions 102 a, 102 b, and pads 108 for the cup portions 102 a, 102 b. Shoulder straps 106 a, 106 b may also be provided such that shoulder strap 106 a connects between cup portion 102 a and side wing panel 104 a and shoulder strap 106 b connects between cup portion 102 b and side wing panel 104 b. The pads 108 are formed of a sustainable material that provides both cushioning and support for a wearer's breasts. The remainder of the bra garment 100 may be formed of recycled materials and/or sustainable materials. As such, the entirety or substantially the entirety of the bra garment 100 can be formed of only sustaining and recycled materials.

The sustainable material in accordance with the present disclosure is a biobased material that is non-toxic to the wearer and may also be devoid of fossil-fuel-based foam material and the like. The sustainable material used to form the pads 108, for example, can have hardness and density values sufficient to provide both cushioning and support to the wearer. And the sustainable material for the bra garment 100 can be manufactured by a sustainable and environment-friendly process.

The sustainable material in accordance with the present disclosure is one that is ecological, friendly, climate-friendly, green, environmental, environmentally-sound, fuel-efficient, energy-efficient, non-polluting, organic, and energy-saving. The sustainable material is a material that can be viable, continuous, continual, feasible, unceasing, livable, supportable, imperishable, unending, renewable, and green. A sustainable material is produced based on available resources to meet current needs while ensuring that adequate resources are available for future generations. In an example, the sustainable material can be a sugar cane or corn-based polymer. Also, biodegradable additives can be added to the sugar cane or corn-based polymer.

The cup portions 102 a and 102 b and the side wing panels 104 a and 104 b may be formed of a recycled material, such as a recycled fabric. A recycled material in accordance with the present disclosure is one that is waste converted into usable material. Recycled fabrics are waste products or fabrics and textiles that can be sorted, graded and reused again to make recycled fabrics, such synthetic fibers like polyester, nylon, and the like.

Each of the cup portions 102 a, 102 b of the bra garment 100 has an outer piece 120 and an inner piece 122 that can be attached, such as by sewing, to one another at respective perimeters thereof forming a pad receiving area 124 therebetween in which respective pads 108 are contained, as seen in FIG. 5. The outer piece 120 may have a generally convex shape selected from a number of available breast cup sizes. The inner piece may have a generally concave shape selected from a number of available cup sizes. The outer and inner pieces 120 and 122 are formed of one or more flexible materials. In an example, the outer piece can be formed of nylon or recycled nylon and the inner piece can be formed of polyester or recycled polyester. The polyester can be brushed for added softness against the wearer's skin.

Each of the pads 108 has front and back surfaces 110 and 112 that correspond to the outer and inner pieces 120 and 122, respectively, of the cup portions 102 a, 102 b. The front surface 110 of each pad 108 has a generally convex shape and the back surface 112 of each pad 108 has a generally concave shape, as best seen in FIG. 5. The size of the pad 108 can be any breast cup size and generally corresponds to the size of the outer and inner pieces 120 and 122 of the cup portions 102 a, 120 b.

Each of the pads 108 is formed of a sustainable material that is a bio-based or Green EVA polymer material with hardness and density values that provide both cushioning and support to breasts of a wearer of the sustainable bra garment, and that is non-toxic to the wearer. For example, the sustainable material of the pads 108 may be comprised of between about 60 to 85% sugar cane polymer. This ratio of the sustainable material provides the desired flexibility to the pads 108 as well as providing comfort and cushioning and sufficient support to the wearer.

In an example of a preferred embodiment, the pads 108 are formed only of the sustainable material that is polymerized using between 60% to 85% bio-based EVA (eg. A sugar cane-based polymer). The bio-based EVA is polymerized by combining said sustainable substance (in the form of sugarcane ethanol) with an initiator, such as a hydrogen peroxide (or bis peroxide) and a blowing (or foaming) agent, such as an azodicarbonimide, as well as other chemicals and additives known in the art, such as a titianium dioxide which may be used as a coloring pigment. The method of the present invention includes heating the bio-based EVA mixture from room temperature to about 125 degrees Celsius (about 260° F.) to create a melt mixture that resembles the consistency of a dough. Such bio-based EVA material is then compressed using a pass-through pressing belt to form a substantially flat sheet. The volumetric shape of the substantially flat bio-based EVA sheet is then expanded through a two-step heating process comprising: 1) heating said sheet to about 130 degrees Celsius (about 265° F.) for about 25 minutes to obtain a volumetric expansion of about 90%, and 2) re-heating said sheet to about 175 degrees Celsius (about 350° F.) for about 45 minutes to obtain a second volumetric expansion of about 200% to form a bio-based EVA foam sheet. An example of a resulting bio-based EVA foam sheet 115 is shown in FIG. 6, which can be used as material for forming one or more pads 108.

The bio-based EVA foam sheet 115 is then formed into partial pad portions 115 a and 115 b by a molding method comprising: 1) heating a portion of said bio-based polymer foam sheet within a mold to about 160° C. (320° F.) for about 2 minutes, and 2) cooling said bio-based polymer foam sheet within said mold to about 10° C. (50° F.) for about 2 minutes; such that each said partial pad portion (115 a and 115 b) is formed within said mold into a shape having an inner surface substantially concave in shape and an outer surface substantially convex in shape and resulting in pad portions having preferred Asker hardness values of about 15 to about 25 on an Asker C scale. Examples of partially formed pad portions 115 a and 115 b are shown in process in FIG. 7 after forming of the pad cup portions using the above preferred molding methods.

An example of a finished pad portion 108 made in accordance with the above processing methods is shown in FIG. 8. The above-preferred processing methods can yield pad portions having various cup sizes. Several such pad portion samples were subjected to a SATRA test method to assess a preferred range of pad material hardness properties. The material hardness of each sample ranging from cup sizes of 32 A to 40 DD was determined at various surface points by subjecting samples to a SATRA TM205:2016 test method using a durometer having an Asker C scale to measure the material hardness. It was determined after such hardness testing that a range of Asker C hardness values of between about 17 to about 22 resulted in preferred material hardness values to provide both appropriate cushioning and sufficient support for the breasts of a wearer of a sustainable bra garment or other garment in which such pads 108 are incorporated.

The front surface 110 of each pad 108 may also be laminated to assist with application of the outer piece 120 of the cup portions 102 a, 120 b. The back surface 112 of each pad 108 may be devoid of any lamination. Alternatively, each pad 108 can be devoid of any lamination altogether, i.e. on either the front or back surface 110 and 112 thereof.

Each of the side wing panels 104 a, 104 b is connected to an outer edge of a respective cup portion 102 a, 102 b. The side wing panels 104 a, 104 b can be formed of one or more fabrics, such as nylon, recycled nylon and the like. The side wing panels 104 a, 104 b can be made of the same or different recycled fabric as that of the cup portions 102 a, 102 b. Also, recycled yarns may be used for sewing the perimeters of any of the portions or panels of the bra garment 100, such as the perimeters 109 around the side wing panel 104 a, 104 b. The free ends of the side wings panels 104 a, 104 b include corresponding clasp elements 130 and 132, respectively, such as hook and eye elements, for clasping the free ends together in a conventional manner. The clasp elements 130 and 132 may be formed of recycled materials, such as recycled metal for the hook, and fabric or yarn for the eye.

The shoulder straps 106 a, 106 b may be formed of recycled materials, such as a recycled elastic material, such as recycled yarns and the like, to provide flexibility and comfort to the wearer. Each shoulder strap 106 a and 106 b may be adjustable using adjustable elements such as corresponding ring and hook members 134 and 136, which function as is known in the art. The ring and hook members 134 and 136 may be formed of a sustainable material, such as a sugar cane polymer. The sugar cane polymer of the ring and hook members 134 and 136 would be harder and more rigid that the sugar cane polymer which forms the pads 108. That is, the sugar cane polymer of the ring and hook members 134 and 136 have a sufficient hardness value and rigidity to couple to the shoulder straps 106 a, and 106 b to allow adjustment thereof.

The bra garment 100 may include an underwire, as seen in FIGS. 1 and 2, or the bra garment 100′ may not have underwire, as seen in FIGS. 3 and 4. The bra garment 100 has an underwire channels 140 a, 140 b at the bottom of supports 102 a, 102 b, respectively. The underwire channels 140 a, 104 b may be formed of recycled fabrics, such as recycled yarns, and are sized to receive a conventional underwire. A bridge panel 138 extends between the underwire channels 140 a, 140 b to join the cup portions 102 a, 102 b. The bridge panel 138 can be formed of a recycled material, such as recycled nylon.

The bra garment 100′ as seen in FIGS. 3 and 4, is substantially the same as the bra garment 100 of FIGS. 1 and 2, except that it does not have an underwire or underwire channels. The cup portions 102 a′, 102 b′ of the bra garment 100′ are the same as cup portion 102 a, 102 b, except that the cup portions 102 a, 102 b′ are sewn together, using recycled yarn for example, at a center line 150 and a bottom line 152, as best seen in FIG. 4. An optional lace trim 154 may be provide at the top of the cup portions 102 a′, 120 b′. The lace trim 154 can be formed of a recycled material, such as recycled yarn and the like.

It will be apparent to those skilled in the art having the benefit of the teachings presented in the foregoing descriptions and the associated drawings that modifications, combinations, sub-combinations, and variations can be made without departing from the spirit or scope of this disclosure. Likewise, the various examples described may be used individually or in combination with other examples. Those skilled in the art will appreciate various combinations of examples not specifically described or illustrated herein that are still within the scope of this disclosure. In this respect, it is to be understood that the disclosure is not limited to the specific examples set forth and the examples of the disclosure are intended to be illustrative, not limiting.

The following definitions and terms are used in this disclosure:

-   -   EVA: As used in this disclosure, “EVA” is an acronym known and         used in the art as a reference to “ethylene-vinyl-acetate”, an         elastic petroleum-based polymer that can be used to produce         materials and products with a rubber-like softness and         flexibility.     -   Green or Bio-based EVA: As used in this disclosure, “Green EVA”         or “Bio-based EVA” is used to describe a carbon negative         material made substantially from sugarcane (sugarcane ethanol)         and used as an alternative and/or substitute for a         petroleum-based polymer. Existing bio-based EVA materials are         available commercially and are supplied by Braskem as an EVA         resin. Preferred resins are identified as EVA Evance SVT 2145         and SVT 2180, which are typically in the form of foam sheets for         use in the soles of footwear products, or in toys and furniture.     -   Hydrogen peroxide or bis (triflourmethyl) peroxide: As used in         this disclosure, “hydrogen peroxide” or “bis peroxide” is used         to describe a chemical used as an initiator (or catalyst) for         the polymerization of unsaturated ethylene-like molecules for         the production of stable polymeric materials, including as an         initiator for Bio-based EVA materials.     -   Blowing or Foaming Agent: As used in this disclosure, a “blowing         agent” or “foaming agent” is used to describe chemical         compositions used in state-of-the-art polymerization processes,         typically an azodicarbonimide, capable of producing a cellular         structure through a foaming process to reduce density and         increase relative stiffness of a base polymer.     -   Titanium dioxide or titanium IV oxide [TiO2]—As used in this         disclosure, “titanium dioxide” or “titanium IV oxide” is used to         describe a substance typically used as a pigment (also known as         “titanium white”) for paints and polymers.     -   Asker Hardness—As used in this disclosure, “Asker Hardness” is         used to describe the measure of hardness of a given material (or         how resistant it will be to permanent indentation), measured by         the depth of indentation that is created on the material with a         specified force. The measuring instrument typically used is         known as a durometer, and different respective scales for         measuring hardness (such as Asker, Shore, Rockwell hardness         scales) are known in the art. Accordingly, different hardness         scales are used for measuring the solidity of different         materials with varying properties, like rubbers, polymers and         elastomers. The most commonly used scales for measuring the         hardness of rubber materials are the Asker C and Shore 00 or A         scales for softer materials and the Shore D scale for harder         materials. The Asker C scale is generally used for measuring         hardness of more flexible foam or rubber materials.
